Silicon carbide, 99% (metals basis)

Description

CAS: 409-21-2 | CSi | 40.10 g/mol

Silicon carbide powder is used as an abrasive for such as grinding wheels, whetstone, grinding wheel and sand tiles. Silicon carbide is used to produce epitaxial grapheme by graphitization at high temperatures. It is also acts asthe metallurgical deoxidizer material. Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials. High purity single crystal, is used to manufacture semiconductors, manufacture of silicon carbide fibers. Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high temperature resistant to oxidation.
